A standard electric vehicle (EV) automotive battery can be decomposed into cell level, module level, and pack level. A cell mainly includes the anodes and cathodes, a module includes multiple cells, and a pack includes multiple modules. The three most common metal-to-metal joints in a lithium-ion battery pack are foil-to-tab, tab-to-tab, and tab-to-bus. All three […]
Read MoreRecently, EWI conducted a study in which ultrasonic vibrations were applied to the wire drawing process to improve both final wire quality and process performance. This investigation demonstrated positive results in several areas including wire roughness, dimensional accuracy, microstructure, draw force, and strength. It also reduced the number of die passes required to complete the […]

Read MoreAccording to a report recently published by Fortune Business Insights,1 market demand for vehicle electrification was estimated at 8.6 million units in 2018. This market is projected to exhibit a compound annual growth rate of 21.1% in the forecast period, 2019-2026 and reach 40.6 million units by 2026. A big part of this market is […]
Read MoreIt is well known that variation in amplitude can affect the consistent performance of an ultrasonic system for use in industry. In ultrasonic-assisted drilling (UAD), this matter is even more critical. Due to the unavailability of the drill tip during the drilling process, it is extremely difficult to measure varying process parameters such as load […]
Read MoreTemperature Measurement in the Ultrasonic-assisted Drilling Process, a paper by EWI Project Engineer Amin Moghaddas, A.Y. Yi of The Ohio State University, and EWI Principal Engineer Karl Graff, has been published in THE INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY. The ultrasonic-assisted drilling (UAD) process is being developed due to its apparent advantages over the conventional […]
